3D reconstruction of rib cage geometry from biplanar radiographs using a statistical parametric model approach
Rib cage 3D reconstruction is an important prerequisite for thoracic spine modelling, particularly for studies of the deformed thorax in adolescent idiopathic scoliosis. This study proposes a new method for rib cage 3D reconstruction from biplanar radiographs, using a statistical parametric model approach. Simplified parametric models were defined at the hierarchical levels of rib cage surface,...
متن کاملFast 3D reconstruction of the spine from biplanar radiographs using a deformable articulated model.
This paper proposes a novel method for fast 3D reconstructions of the scoliotic spine from two planar radiographs. The method uses a statistical model of the shape of the spine for computing the 3D reconstruction that best matches the user input (about 7 control points per radiograph). In addition, the spine was modelled as an articulated structure to take advantage of the dependencies between ...
متن کاملAutomatic Femur Condyles Disambiguation for 3d Reconstruction from Biplanar Radiographs
3D bone reconstructions from biplanar radiographs showed an increasing interest in the last decade. Three-dimensional (3D) reconstruction process of the femur as proposed by recent works (Chaibi et al., CMBBE, 2011) relies on the identification by an operator of a few landmarks on the radiographs to initiate the procedure. Among others landmarks, the operator needs to identify the medial and la...
متن کامل3D biplanar statistical reconstruction of scoliotic vertebrae.
A new 3D reconstruction method of scoliotic vertebrae of a spine, using two calibrated conventional radiographic images (postero-anterior and lateral), and a global prior knowledge on the geometrical structure of each vertebra is presented. This geometrical knowledge is efficiently captured by a statistical deformable template integrating a set of admissible deformations, expressed by the first...
متن کاملTowards Model-based 3-D Reconstruction of the Human Rib Cage from Radiographs
This work is concerned with the three-dimensional (3-d) shape and pose reconstruction of the human rib cage from few two-dimensional (2-d) radiographs. The reconstruction method is based on a statistical shape model of the rib cage that is adapted to the 2-d image data of a patient. An underlying optimization process minimizes a distance measure which quantifies the dissimilarities between 2-d ...
